Process for extracting gold, silver, platinum, lead, or ...

Nov 22, 1983 · One extraction method which has been known since the beginning of written history is the use of metallic lead (Pb) as an extraction material. Metallic lead has a particular affinity for various metals including, gold, silver, platinum, manganese, and lead itself. It was recognized early that the use of elemental lead could aid in the extraction of these metals from their ores.

The heating of lead dross in the reverberatory furnace separates the lead bullion (rich in lead), matte (copper and other metals sulfides) and speiss (high in arsenic and antimony contents). Matte and speiss are treated in copper smelters for the extraction of copper and other associated metals [58].

gold, silver, copper, tin, lead, and iron. Gold and silver were too soft to be useful for much except decoration. Copper could be hardened by ham-mering or forging and was therefore useful as a tool but had little value as a weapon. Bronze, developed by alloying copper with tin, had use-ful strengths, could be hardened by forging, and

The Silver Extraction Process. Since lead was also valuable, it was recovered by placing the litharge (lead oxide) remaining from the cupellation process into yet a third furnace and heated to 250 degC and air was blown through it. The lead was run-off and formed into rods. Since lead is a cumulative poison,...

Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium. An important sulfide mineral common in waste rock is pyrite, iron sulfide. When pyrite is exposed to air and water, it undergoes a chemical reaction called "oxidation."
